di SQL
-- The difference is that BETWEEN will search for all the values that fall
-- between the mentioned lower and upper bound.
-- However, IN will only search for the mentioned list of values in your DB.
select Name from Student where Marks between 75 and 100
-- BETWEEN allows you to test if an expression is within a range of values
-- (inclusive). In our case the value has to be >=75 & <=100
select Name from Student where Marks in (75,80,85,90,95,100)
-- IN allows you to test if the expression matches any value
-- in the list of values.
-- NOTE: If a student has lets say 81 marks, they will appear after the
-- line having BETWEEN operator is executed, but not when the line having
-- IN operator is executed.
